Specification of Letters Patent.

Patented Aug. 20, 1918.

Application filed .Tune 26, 1916. Serial No. 105,792.

To all Z whom it may concern:

Be it known that I, CURTIS W. SHIELDS, a citizen of the United States,residing in Brooklyn borough, in the county of Kings, city and State ofNew York, have invented certain new and useful Improvements inType-Writing Machines, of which the following is a specification.

This invention relates to means for use with typewriting machines, tofacilitate a quick and accurate adjustment of worksheets on the platenin position for being written upon, particularly where such sheets areplaced on the machine a number of times, the sheet being adjusted ateach new insertion to a difl'erent or more advanced position,corresponding to the increase in the typewritten matter thereon.

The invention is also advantageous for use in work in which a number ofthe sheets are placed on the machine together in different positions ofadvancement, and especially where one or more of said sheets arerepeatedly placed on the machine, each time in' a different positionrelatively to other sheets collated therewith, as is customary forexample, in some systems of bookkeeping. I

An object of the invention is to provide means, operative upon awork-sheet while the latter is on the machine, to produce animpressionon the sheet which will later serve as a gage in adjusting thesheet on the platen. Such impression may be made at a positioncorresponding to the advancement of the sheet in line-spacing direction,at the completion of the typewritten matter, before the sheet isremoved, so that when the sheet is again placed on the machine to befurther written upon, it may be quickly and accurately adjusted by meansof said impression,

to a position corresponding to the position of the last ty ewrittenline.

More speci cally, the inventionmay comprise a cutting or punching deviceor devices operable as the work-sheet-is advanced. around the platen,'toshear or punch porby leaving upon the edges of the work-sheet gagingsurfaces or shoulders at positions corresponding to the advancement ofthe sheet, said cutting devices themselves preferably serving as gages,so that the sheet,

after it has been removed from the machine, may again be placed thereonand gaged or brought to the position it occupied before it was lastremoved. The combined cutting and gaging devices may be located, one ateach end of the roller platen and arran ed to be operated by the usualline-spacing mechanism to out or trim off a section of each side marginof the work-sheet at each line-spacing operation. A narrow strip ofwaste may thus be trimmed off each side margin little by little as thepage is written. This operation leaves shoulders or jogs in thesheet atthe termination of the trimmedofi' portions. Hence, each sheet hasopposite shoulders on its side edges at positions therealongcorresponding to the position of the last typewritten line. Theseshoulders are naturally in engagement with the ends of the punches, andthe latter thus form gages en a number of sheets have been placed on themachine and written upon, the under sheet may be allowed to remain inthe machine while a fresh top sheet is substituted,

set immediately to position to write the next line thereon. This topsheet may have been partly written before, so that it is provided withalining shoulders or jogs. Said-sheets may also be manufactured. withtheir upper edges trimmed off to form gaging shoulders which, whenadjusted to the punching gages, position the sheet for the first line ofwriting. I

The sheet-gaging cutters or punches may be arranged to be operated bythe usual linespacing lever. The latter has an f initial movement duringwhich the platen remains at rest, while the cutters are swung tocutting. and gaging position, and then released and swungout of the pathof the worksheets before the latter are advanced bythe line-spacingmechanism. A key may be provided to silence the cutting and gaginghaving jogs or shoulders whereby it can be sheets are placed on theplaten, they may be drawn forward until arrested by said gages,

in position to be written upon. The feedroll release key may then bereturned, thereby causing the feed rolls to clamp the sheet in positionon the platen and cause the gaging devices to be withdrawn.

A key may be provided to actuate the cutting gages independently of theline-spacing mechanism and the feed-roll release key.

Other features and advantages will hereinafter appear.

Fig. 11 is a sectional view as indicated by the section line 1111 onFig. 2.

A rotary platen 12 may be fixed to the platen axle 13 journaled in theends 14 and 15 of a platen frame. An inclined papershelf 16 at theintroductory side of the platen aavaars may form part of the platenframe. Typebars 17 (Fig. 2) may be operated by the usual mechanism, tocause the types thereon to strike against the front face of the platen.The platen frame and platen may be shiftable to upper and lower-casepositions on the carriage frame 18. The carriage may be mounted on themachine frame for letterfeed travel, the usual mechanism for drivingmoves rearwardly a slide bar or driver 22 on which is pivotally mounteda dog 23 to engage and drive a line-space ratchet wheel 24 xed to theplaten, and thereby rotate the platen. The line-spacing lever and saiddriver may be returned by a spring 25. The stroke of the line-spacingpawl is regulatable as usual for 1, 2 or 3 spaces by a bandle 20 Thework-sheets may be placed on the paper-shelf 16 and. advanced around theunder side of the platen, and upwardly over the front -face of theplaten to writin'g position, being guided between the platen and a guideplate 26 forming a continuation of the shelf 16.

Platen feed rolls 27 and 28 normally bear upon the under surface of theplaten and cooperate therewith to feed the work-sheets asthe platen isrotated. Said feed rolls may be thrown ofi' the platen to permit theworksheets to be adjusted on the platen "or removed while the platen isat rest. For this purpose, a feed-roll release key 29 is pivoted at 30on the platen frame, and comprises an arm 31 connected througha link 32to a rock arm 33 on a rock shaft 34. The feed rolls are mounted onshafts 35 Sup ported in levers 36 pivoted on a rod 37, said leverscomprising arms 38 which may be spread by means of flats or cams 39 onthe rock shaft 34. Thus when the key 29 is depressed to the Fig. 5position, the feed rolls 27 and 28 are thrown elf the platen and held insuch position'until an upward pressure is applied to the key 29 torestore said rolls to narrow strip off each side edge of the work-' Isheets on the platen, the length of each section or cutting being ofcourse equal to a line-space distance, or the distance the worksheet isadvanced by an operation of the linespace lever. By this operationshoulders or gaging edges 41 are formed on the margins of thework-sheets, such gaging shoulders thus always having a fixed relationto the last typewritten line on the work-sheet.

The cutting devices 40 serve as gages to which the gaging edges 41 maybe adjusted, so that if a work-sheet .has been written upon by themachine and then removed, the gaging shoulders 41 formed durlng thelinespacing operations, provide a means by which the sheets may bequickly and accu-- rately adjusted, when again placed 'on the machine,to a position determined by the position of the last typewritten l1neupon the sheet.

The cutters or punches 40 are each mounted on a rock arm 42, said armsbeing fixed to a rock shaft 43 which may be journaled in the ends of thelaten frame. The shaft 43 ma be rocked y means-hereinafter describe toswing the punches or dies 40 downwardly into die-openings 44 formed indie-plates 45, each of which may be'in the form of a ring mounted on anannular flange or projection 46 formed on a supporting plate 14 attachedto the adjacent platen frame end and projecting inwardly from said platetoward the platen. The rings 45 may be of the same diameter as theplaten l2 and concentric therewith, said rings abutting against the endsof the platen and forming a supportin surface or backing for the marginsof t e work-sheets which project beyond the end of the platen. Each ring45 may be secured to its supporting annular flange 46 by clamping screws47, which extend freely through openings 48- in the ring 45 and arethreaded into the flange 46. The openings 48 may be elongated to permitrotative adjustment of the said ring to accurately register thedie-opening 44 with the cutter 40.

The mechanism through which the linespace lever is operative to actuatethe cut-- ters, will now be described. The forward end 49 of the slidebar 22, which is bent inwardly to extend perpendicular to the body ofsaid bar, thereby providing a shoulder against which the arm 21 bears,is utilized to actuate the cutters. For this purpose, an arm 50 (Figs.2, 4 and 8) connected by a pivot 51 to a rock arm 52 on the shaft 43,extends forwardly from its pivot, with its forward end supporteddirectly behind the end 49 of theslide'bar 22 to be actuated thereby.The cutters 40 are. normally held end of said spring being connected tothe platen. This idle or lost motion is utilized to actuate the cutters40, as it is obviously desirable that thecutting or punching op-.eration should be effected and the cutters withdrawnfrom the path of thework-sheet while the platen is still at rest.

As shown in Fig. 2, the end 49 of the slide bar 22 is directly in frontof the forward end of the arm 50, so that as said slide bar movesrearwardly from its starting position 49, Fig. 4, to the full-lineposition,

the arm 50 is also moved rearwardly and operates through the arm 52'torock the shaft 43' and swing the cutters inwardly,

thereby cutting a section of]? each side margin of the work-sheet. Theparts are so timed that the cutters 40 have completed their operativestroke by the time the linespa'cing pawl 23 has been brought to positionto drive the ratchet wheel. In order to release the arm 50 from thedriver 49 at or before'this time, said arm 50 is provided with aforwardly and upwardlv inclined cam surface 55 beneath a pin 56 on theplaten frame. As the arm 50 is moved rearwardly, it is at the same timecammed downwardly by said pin, and as it reaches the Fig. 4 position isdisengaged from the driver 49, permitting the latter to continue itsforward movement to the 49 position, thereby line-spacing the platen,while, the arm 50 being released, the spring 53 throws the cutters backto starting position. VVhen the driver 49 is returned to its initialpositlon 49 (Fig. 4), the arm 50 is thrown upwardly to the Fig. 2position, by means of a leaf-spring 57. Said spring 57 is connected wltha swingin arm or latch 58, connected by a pivot 59 wlth the arm 50. Saidarm 50 is held with a yielding pressure against the pin 56 by means ofthe spring 57, the forward end of which is supported on a pin 60 in thearm 50.

The operation of thecutting device, in conjunction with the line-spacingoperation, may be briefly reviewed as follows: lVhen the line-spacelever is operated, the movement of the driver thereby from the startingposition 49" (Fig. 4) to the full-line position (Fig. 4), swings thecutters 40 111- wardly, causing each cutter to sever from the margin ofthe work-sheet a strip equal in length to a line-space distance. As thedriver 49. reaches the full-line position (Fig.

4), the arm 50 is carried below the driver, the cutters are snappedupwardly by the spring 53 out of the path of the work-sheet, and thedriver, as it continues its forward movement, rotates the platen,line-spaces the work-sheets, and brings a new portion of the marginsbelow the cutters. The ring 45 and flange 46 may be provided with anopening 61, through Which the punchings may fall.

The cutting gages 40 may be operated independently of the line-spacingmechanism by means of a key 62 fixed to the rock shaft 43. When it isdesired to operate the linespacing mechanism, without operating thecutting gages, a key 63 is depressed to silence the gages. This key(Figs. 2 and 10) is povoted at 64 on the platen frame, and comprises adepending arm 65 provided at its lower end with an inclined cam face 66,which, as the key is depressed, is swung forward and strikes a. pin 67on the arm 50, thereby swinging said arm downwardly to the Fig. 10position, in which it is held below the driver 49, so that theline-space lever may be operated without affecting the cutting gages.When the key 63 is fully depressed, the cam surface 66 is carried beyondthe pin 67, so that the latter bears against a dwell surface 68. The key63 is held in either its depressed position or its normal inoperativeposition by a spring detent arm 69, having a detent to seat in notches70 in the platen frame.

The gages 40 may also be actuated by the platen-feed-roll release key29. To this end,

the arm 31 (Fig. 9) of the release key lever has fixed thereto anextension 71, provided with a cam surface 72, which, when the key 29 isdepressed, strikes a pin 73 on a rock arm 74 on the shaft 43, and rockssaid shaft to swing the cutters to the Fi 5 position. The pin 73 nowrests against a well surface 75, thereby holding the gages 40 inoperative position until the key 29 is returned. It will be seen, byreference to Fig. 9, that the key 29 is depressed sufiiciently to throwthe feed rolls off the platen before the gages are operated. In otherwords, the feed rolls may be moved to and from the'platen withoutoperating the gages. Each cutter comprises a longitudinal cutting edge76 (Fig. 9) and a transverse cutting edge 77 (see also Fig. 11). Thelatter edge at each out forms the gaging edge or shoulder 41 on thework-sheet. The cutting edges 76 and 7 7 are preferably both inclined soas to produce a shearing cut. The outer end face 78 of the cutter blockis preferably curved in an arc concentric with the pivot shaft 43, and,when the cutters are swung inwardly, provides a gage or abutment towhich the sheets may be gaged, as hereinafter pointed out. Guide plates79 may be located below the gages 40 and extend within a short distanceof the gates, said guide aaraaae plate being spaced from the ring 45 topro vide a guideway for the margins of the worksheets. Said guide platesserve to hold the sheets close to the ring 45 at the gages, thussecuring accuracy and uniformity of the gaging operations.

Fig. 6 indicates a method of arranging and gaging a number of thework-sheets on the platen prior to typewriting thereon. These sheets a,b and c may all be placed on the platenat the same time, and thenindividually adjusted and gaged on the platen by bringing the gagingshoulders 41 on the sheets up to the gages 40. That is, after the sheetshave been placed on the platen, the innermost sheet a, for example, maybe grasped at its leading edge (either at the middle or at one or bothcorners) and drawn upwardly until the shoulders 41 thereof are broughtup to the gages 40. The sheets I) and 0 may in turn be gaged in likemanner. The sheets are thus collated and gaged so that each sheet is inproper position for receiving typewritten matter directly below the lastline typewritten thereon before the sheet was removed from the machineat a preceding operation. It will be understood that carbon sheets 80are interposed between the several work-sheets a, b and c, and arenarrower than the work-sheets, so that they are not affected by thecutters.

Prior to placing the sheets on the platen as shown in Fig. 6, thefeed-roll release key 29 may be depressed to the Fig. 5 position,thereby throwing the feed rolls off the platen, enabling the sheets tobe quickly placed on the machine without rotating the platen, the gages40 by such depression of the key 29 being brought to operative position.When the sheets have been individually adjusted to the gages, as abovenoted,

the release key 29 is lifted to return the feed rolls and clamp thework-sheets to the platen, and at the same time withdraw the gages to aninoperative position. The llnespace lever is operated after thecompletlon of each typewritten line, to advance the work-sheets andconcomitantly operate the cutters. After the last line has beentypewritten, the line-space lever may again be operated before removingthe sheets, to bring them to the position they will occupy when againplaced on the machlne and adjusted ready to be written upon. The key 29may then be operated, before wlthdrawing the sheets, to lift the feedrolls and at the same time operate the cutting gages 40, so that whenthe sheets are again placed on the machine and adjusted to the gages,they are in position to be written upon without operating theline-spacing lever.

The work-sheets, if desired, may be provided with rows of perforations81, ermitting marginal strips to be torn ofi', after the typewrittenentries on the sheet have been ledgers or the like.

formed to provide gaging edges 41 in such I position that when the sheetis placed on the platen and adjusted to bring the edges 41 to the gages40, the sheet is in proper position to receive the first typewrittenmatter. Such sheets may be prlnted bill-heads, invoice-sheets or otherprinted forms, or plain sheets.

The present invention is particularly useful in work wherein a number ofsheets are placed together on the machine, with their leading edges atdifferent positions of advancement, as is customary in some systems ofbookkeeping and in other Work. Thus, for example, it i customary toplace a record sheet, such as b (Fig. 6), together with an overlying orunderlying bill or invoice,

I to receive typewritten entries. The record sheet may receive theentries made on a num- .ber of different bills or invoices, so that saidrecord sheet may be placed on the machine many times, and each time in ad fferent position relatively to the accompanying bill or invoice-sheet.The present invention permits all the sheets to be placed on the machineat once and quickly adjusted, to bring the individual sheets, each to aposition corresponding to that of the last written line thereon, withoutrequiring the operator to see the typewrittenmatter on the sheet, whichmay be hidden by an overlying sheet. The work-sheets may be manufacturedwith gaging shoulders 41 as indicated in Fig. 7, in such position thatwhen the sheet is gaged thereby on the machine, it Wlll be in positionto receive the first line of writing. The sheet may have a printedheading, including a date line as shown, which will be positioned at theprinting line on the platen when the sheet is gaged by means of saidshoulders 41.

Although,-for the purpose of construction, the cutting edges 76 and 77are on the same block that forms the gage, that is to say, the cutterand gage are formed of'one piece,

yet the function of the cutter is entirely distinct from that of thegage, and said elements do not-need to be formed as a single part in allcases. By curving the surface 78 of the gage concentrically with thepivot shaft 43, as before noted, the gaging surface serves to positionthe sheets at the precise position they occupied when operated upon bythe cutters, although this is not necessary in all cases, nor is itessential that the position to which the sheets will be gagedbe the sameas that occupied by the sheets when operated upon by the cutters, northat the cutters and gage be simultaneously operated.

Variations may be resorted to within the scope of the invention, andportions of the improvements may be used without others.

Having thus described my invention, I claim:
